Is the TOTO Neorest WX2 Worth It?
Yes — if you are designing a modern luxury bathroom from scratch and want the most advanced wall-hung smart toilet money can buy, the WX2 is absolutely worth it.
But that “if” carries a lot of weight.
The WX2 is not a simple upgrade from a standard toilet — it is a full bathroom construction project.
You need a properly framed wall, a licensed plumber for the in-wall tank, and a GFCI electrical outlet nearby.
If you are mid-renovation and building the bathroom you have always wanted, the WX2 is the logical endpoint of every smart toilet feature TOTO has ever developed — all packed into one floating, nearly autonomous unit.
If you are looking for a simpler path to a premium bidet toilet experience, there are excellent floor-mount integrated options like the highest-rated bidet toilets we cover in our dedicated guide, including the Neorest RS, AS, and LS.
But if you want the wall-hung look and you want ACTILIGHT — the WX2 is the only choice in wall-hung form.
Design & Build: The Floating Toilet That Looks Like It Belongs in a Museum
The Neorest WX2 has a design philosophy that most toilets do not attempt: complete invisibility of function.
From the outside, it looks like a single smooth ceramic form floating off the wall.
There are no visible hinges, no tank, no exposed plumbing — the entire mechanical system lives inside the wall via the included WT175MA in-wall tank unit.
The skirted bowl hides every trapway and joint, and the seamless seat design closes the gap where most toilets collect grime.
This is the wall-hung equivalent of the floor-mounted Neorest NX series — essentially the same feature set and design DNA, but mounted to the wall for a completely different spatial experience.
If you have ever compared the best toilets with a built-in bidet, you know that aesthetics matter enormously at this price point — and the WX2 delivers one of the cleanest silhouettes in the category.
The adjustable mounting height is a particularly thoughtful engineering detail.
You can set the finished rim height anywhere between 15 and 19 inches from the floor, making it genuinely accessible for users of all ages — a feature that anyone researching bidets for seniors will immediately appreciate.
Cleaning Performance: The Self-Cleaning Toilet That Actually Cleans Itself
The WX2’s signature feature is ACTILIGHT® — and it is the main reason you would choose this model over the WX1.
ACTILIGHT works by combining a special zirconium coating fired into the ceramic bowl with a UV light built into the lid.
Every time the lid opens, the UV light activates and triggers a photocatalytic reaction in the zirconium coating — this breaks down waste and bacteria at a microscopic level, keeping the bowl cleaner between manual cleanings.
No chemicals involved — just light, oxygen, and water.
This is the same ACTILIGHT technology found in the floor-mounted Neorest NX2, and if you’ve been following TOTO’s ceramic technology, you’ll know that the zirconium coating also works synergistically with CEFIONTECT® — the ultra-smooth ion-barrier glaze that prevents waste from sticking to the bowl surface in the first place.
Layer that with PREMIST® (which mists the bowl with water before every use so waste slides away cleanly) and EWATER+® (which mists the wand, bowl, and under-seat area with electrolyzed water after every use), and you have the most comprehensive self-cleaning system on any toilet available today.
In practical terms: you will clean this toilet far less often than any standard toilet — and when you do, the job is quick.
Comfort Features: Every Luxury Detail, in One Place
The WX2 covers every comfort feature without exception.
The heated seat adjusts from 82°F to 97°F — five temperature levels so every family member finds their sweet spot.
The instantaneous water heater means warm water starts immediately and never runs out, regardless of how long your wash takes.
This is a significant improvement over older tank-heater bidet seats — if you’ve been researching how the TOTO C5 vs S7 compare on water heating, the WX2 uses the same instantaneous system as the flagship S7, scaled up for an integrated unit.
The warm air dryer runs across five temperature settings from 95°F to 140°F — more than enough range to fully dry without any toilet paper needed.
The automatic air deodorizer activates the moment you sit down and runs continuously until you rise, so there’s nothing to remember or press.
A soft night light fades on automatically when you approach and fades off when you leave — a thoughtful detail you never knew you needed until you experience a midnight bathroom visit without flipping on a blinding overhead light.
The four-user memory preset system stores each person’s preferred wash position, temperature, pressure, and dryer settings — so every household member steps in and gets their personalized experience immediately.
If you are comparing this to a standard bidet seat setup, our bidet toilet seat comparison chart shows just how far ahead an integrated unit like the WX2 sits on every comfort metric.
Controls & Installation: Effortless to Use, Complex to Install
The WX2’s stick-style ergonomic remote is intuitive from the first use.
Controls are clearly labeled and logically grouped — wash mode, spray position, water temperature, dryer, and flush are all within a thumb’s reach.
The front of the toilet lid opens automatically via proximity sensor — you don’t touch anything from entry to exit.
The automatic dual-flush system even selects the appropriate flush volume (0.8 or 1.2 GPF) based on how long you were seated, with a manual push button on the wall plate as a backup for power outages.
However, installation is a completely different conversation from using it.
The WX2 is not an existing-toilet upgrade — it requires demolition, framing, in-wall tank placement, and professional plumbing.
The WT175MA in-wall tank system needs a framed wall capable of supporting 880 lbs and adequate structural bracing.
If you are in the middle of a bathroom renovation, this is very manageable to plan for.
If you are retrofitting an existing bathroom, you should understand that you are looking at a significant construction project.
For anyone exploring simpler wall-hung options with a WASHLET seat, our comparison of the TOTO AP vs EP wall-hung toilets covers an excellent mid-tier entry into wall-hung bathroom design that doesn’t require this level of structural commitment.

Who Is the TOTO Neorest WX2 Best For?
The WX2 is the right choice if you are renovating or building a master bath from scratch and are committed to the wall-hung form factor.
It is best for buyers who want ACTILIGHT — the active UV self-cleaning system — which is the one feature that separates the WX2 from every other wall-hung smart toilet available.
It is also an exceptional choice for multi-person households that will genuinely use the four individual user presets and benefit from the adjustable mounting height for different heights and mobility needs.
If you’re comparing it purely on technology to a floor-mounted unit, the WX2 sits alongside the Neorest NX2 as TOTO’s absolute best — just in a wall-hung format.
If you want to explore how the broader Neorest lineup compares before committing, our guide to the bidet toilet vs bidet seat decision is a helpful starting point for understanding how much of this investment is truly right for your situation.
And if you’re buying for a household with elderly or mobility-limited users, the WX2’s height adjustability and fully hands-free operation make it one of the most thoughtful choices you can make — pair that research with our guide to best bidets for seniors for the full picture.
FAQ
What is the difference between the TOTO Neorest WX1 and WX2?
The only difference between the WX1 and WX2 is ACTILIGHT® — the UV photocatalytic self-cleaning system built into the lid.
The WX2 has it; the WX1 does not.
Every other feature — EWATER+®, PREMIST®, Tornado Flush®, heated seat, auto lid, dryer, and 4-user presets — is identical between both models.
If self-cleaning bowl maintenance is a priority and justifies the price premium, the WX2 is the one to buy.
Does the TOTO Neorest WX2 work on a round toilet configuration?
The WX2 is an elongated wall-hung integrated unit — it is not a bidet seat that fits onto a separate toilet bowl.
The bowl is part of the unit itself (model CT9548CEFX#01) and comes as a complete package with the top unit and in-wall tank system.
There is no round configuration available for the WX2.
What is ACTILIGHT® and how does it keep the bowl clean?
ACTILIGHT® is TOTO’s UV photocatalytic cleaning system.
The ceramic bowl is fired with a special zirconium coating, and an ultraviolet light built into the lid activates that coating every time you open the lid.
The photocatalytic reaction breaks down waste and bacteria on the bowl surface at a microscopic level — without any cleaning chemicals.
Combined with PREMIST® and EWATER+®, it is the most comprehensive self-cleaning toilet system currently available on any product.
How does the TOTO Neorest WX2 compare to the Neorest NX2?
Both the WX2 and NX2 feature ACTILIGHT® and are considered TOTO’s top-tier smart toilets.
The key difference is installation format: the NX2 is a floor-mounted one-piece toilet that installs like a conventional toilet, while the WX2 is wall-hung and requires a framed in-wall tank system.
The NX2 tends to be slightly more accessible from an installation standpoint — but the WX2’s floating design offers a minimalist aesthetic and easier floor cleaning that the NX2 cannot match.
If you’re weighing these two, it largely comes down to whether your renovation supports in-wall tank installation.
Conclusion
The TOTO Neorest WX2 is as close as bathroom technology gets to a fully autonomous toilet.
ACTILIGHT® handles bowl hygiene with UV light and photocatalysis.
EWATER+®, PREMIST®, and CEFIONTECT® handle everything else.
The floating wall-hung design is stunning, the comfort features are exhaustive, and the four-user preset system makes it genuinely practical for real households.
The honest trade-off is that none of this happens without a major installation commitment and one of the highest price tags in the entire smart toilet category.
But if you are building the bathroom of your life and you want the wall-hung form factor with TOTO’s best self-cleaning technology — the WX2 is the definitive answer.
